configure WPA/WEP in openbsd

25 May 2010

WPA - static ip

Since openbsd 4.4 (4.5 for ath0) it’s possible to connect to wpa networks, it doesn’t work with all drivers but eventually it should be viable with most of them.

$ ifconfig ath0 nwid ACCESS_POINT wpa wpapsk $(wpa-psk ACCESS_POINT PASSWORD)
$ ifconfig ath0 10.0.0.2 255.255.255.0 10.0.0.1

It can also be configured in /etc/hostname.ath0 for connecting at boot time:

$ cat /etc/hostname.ath0
  inet 10.0.0.2 255.255.255.0 10.0.0.255 nwid ACCESS_POINT wpa wpapsk \
  0xc7bd82ef64a789369e18d6df63230a3b099f72a74b999bdbe837773e6081cb54

The last parameter is taken from $ wpa-psk ACCESS_POINT PASSWORD

WPA - dinamic ip

$ ifconfig ath0 nwid ACCESS_POINT wpa wpapsk $(wpa-psk ACCESS_POINT PASSWORD)
$ dhclient ath0

/etc/hostname.ath0:

$ cat /etc/hostname.ath0
  dhcp nwid ACCESS_POINT wpa wpapsk \
  0xc7bd82ef64a789369e18d6df63230a3b099f72a74b999bdbe837773e6081cb54

WEP - static ip

$ ifconfig ath0 nwid ACCESS_POINT nwkey 0xPASSWORD
$ ifconfig ath0 10.0.0.2 255.255.255.0 10.0.0.1

/etc/hostname.ath0:

$ cat /etc/hostname.ath0
  inet 10.0.0.2 255.255.255.0 10.0.0.255 nwid ACCESS_POINT nwkey 0xPASSWORD

WEP - dinamic ip

$ ifconfig ath0 nwid ACCESS_POINT nwkey 0xPASSWORD
$ dhclient ath0

/etc/hostname.ath0:

$ cat /etc/hostname.ath0
  dhcp nwid ACESS_POINT nwkey  0xPASSWORD

The same commands can be used from the installer (by using ! as prefix)
